I am considering piecing together a DIY photobooth for a wedding later this year. Most of the easiest methods for accomplishing this seem to involve using a digital camera which supports both external flash and remote control (ala http://www.instructables.com/id/Instagram-Inspired-DIY-Photo-Booth/). This allows you to provide amble lighting for the shots which are likely being taken in a dark party area or inside a booth, and control the shutter from a USB connected computer which is running the photobooth application.

As I do not currently own a DSLR camera (or one which supports remote shutter) I am wondering what your recommendations might be for the best value if I were looking to purchase a camera explicitly for use in a project like this. New or Used should both be fine...
